Inrarrying my invention into practice it Referring to Figures 1, 2, 3, 4 and 5, my

1 has been my purpose primarily to provide improved burner is shown as comprising an an improved construction of burner of this atomizing casing A and a nozzle B. The type whereby its general efi'ectiveness is enatomizing casing A comprises a cylindrical 7 hanced, which will enable a very fine adbody 15 and end members 16 and 17, said justment to be effected with extended range end members being provided with axially of usefulness, irrespective of wide variation alined passages 18 and 19, respectively, for in the density of oil, which effectively atoma purpose that will presently appear. The izes the oil prior to its passage to the burner end member 17 is provided with an oil pas- 75 nozzle, which can be easily and quickly sage 20 and a steam passage 21. The outer cleaned, and which possesses other advanend. of the passage 20 is connected with an tages as will hereinafter appear. oil supply pipe 22 controlled by a valve 23.

I will describe my invention in the best The outer end of the passage 21 is connected forms known to me at present, but it will be with a steam pipe 24 controlled by a valve so apparent that the same is susceptible to 25 and conne cted with a steam supply ipe changes in forms and proportions and to 26".- Moun ted axially within the casing is 30 desirable additions with the exercise of only a mixture conveying tube 27, one end of ordinary mechanical skill and without dewhich is threaded in the passage 18 of the parting from the scope thereof as set forth, head 16,. while the other end thereof ex- 95 in the appended claims. tends. entirely through the head 17 to the In the drawings chosen to illustrate myv exterior of the casing A. I provide the i ti tube 27 with a spirally arranged row of Figure 1 is a side elevation of my imequidistantly spaced ports 28, said ports deproved burner completely assembled; creasing progressively in cross sectional w Fig. 2, a longitudinal section through the area from one end of the row to the other fuel atomizing casing embodied in my and said ports provide the means whereby burner; r the fuel mixture may pass from the interior 1 Fig. 3, a perspective view of the fuel mixof the casing A to the interior of the tube ture conveying tube associated with the 27.

Fig. 5,"a section on the line 55 of Fig.2; whose long arm extends longitudinally of Fig. 6, a View similar to Fig. 2 showing a the valve and opens through the end thereof modified form ofmy invention; adjacent the head 16, while the short arm Fig. 7 a side elevation of a fragment of of said passage opens through the side of my burner and including another modified the valve and forms a port 31 which is m5 form of atomizing casing; p adapted to be brought successively into is provided with an L-shaped passage 30 we 34 and 35 corresponds to the pitch of the spiral arrangement of the ports 28, so that as the valve 29 is rotated 1n e1ther direction through its prescribed limits by means of of the ports 28 and thereby prevent such the handle 36, it will partake of rotary and longitudinal movement which will bring the port 31 successively into registration wlth the ports 28 of the tube 27. As the ports 28 are spaced equidistantly it W1ll be obvious that successive registrations of the port 31 with the ports 28 will be had by imparting equal predetermined rotations to the handle 36. In the present instance the spacement .between the ports 28 is such that a quarter turn of the handle 36 will move the port 31 from a position of registration with one port 28 to a position of registration with an adjacent port 28. By this arrangement I am able to provide an exceedingly large number of ports 28 varying successively but slightly in cross sectional area and in this manner I am enabled to obtain both a very fine and Wide range adjustment of the burner.

In order to remove accumulated oil from the surface of the tube 27 within the area ports from becoming clogged with oil, I resort to the following construction. Rotatably mounted on the tube 27 adjacent the inner end of the end member 17 of the easing B is a rotor 37 provided with blades 38 with which the steam and oil entering the casing through the passages 20 and 21 is adapted to impact for the purpose of actuating the rotor 37, it being noted that the passages 20 and 21 are disposed substantially tangentially of the rotor so that the steam and oil will impact properly against the blades 38 to effect the necessary rotation.

Also rotatably mounted on the tube 27 isa hub 39 held against longitudinal movement by a collar 40 formed on said tube. The rotor 37 and hub 39 are so spaced as to contain between them the entire area of the ports 28 and this rotor 37 and hub 39 are connected b helical blades 41, the inner edges of which are adapted to wipe the adjacent outer surface of the tube 27 during rotation thereof under the influence of the rotation of the rotor 37 and thus prevent accumulation of oil in the ports 28. In addition, the device formed by the rotor 37,

hub 39 and blades 41 operates during its rotation to materially assist in breaking up the oil thereby effecting a more efiicient atomization. It will also be observed in this connection that as both the oil and steam impact against the blades 38 of the rotor this element alone serves to materially enhance the breaking up of the oil and proper mingling of the particles of oil and steam. In order to provide for effectively cleaning of theatomizing casing A I provide the latter with a cleaning outlet 42 controlled by a valve 43. By opening this valve 43,.shutting oil" the oil supply and turning in the steam supply it will be apparent that any sediment or residue in the casing B will be effectively blown out.

In the modified form of my invention shown in Fig. 6 I provide the tube 27 with a single longitudinal row of ports 44 which successively decrease in cross area from one end of the row to the other. Communication between the casing A and thetube 27 through any desired port 44 is controlled by a valve 45 having a recess 46 which communicates with a port 47 adapted to be brought successively into registration with the ports 44 by sliding movement of the valve exclusively, said valve being held against rotation, by means of a pin 48 mounted in the tube 27 and engaging in a longitudinal slot 49 formed in the valve. The closed end of the valve 45 has threaded therein a screw member 50 which is held against longitudinal movement by a stuffing box construction 51 mounted on the adjacent end ofthe tube 27. By this construction it will be apparent that as the screw member 50 is rotated the valve 45 will be moved longitudinally to bring the port 47 successively into registration with the ports 44 to effect the desired adjustment of the burner in response to the particular oil conditions at hand.

In Figures 7, 8,9, 10 and 11 I illustrate still another desirable form of atomizing casing wherein one end of the casing is closed by a threaded plug 52 which carries the mixture conveying tube 27. Secured against the inner end of the plug 52 by suitable screw 53 is a disk 54 provided with a concentric row of ports 55 which decrease in cross sectional area from one end to the other. In this form of my invention steam and oil is introduced into the casing on the side of the disk 54 which is remote from the tube 27. The ports 55 are controlled by a rotatable disk valve 56 provided Witha port 57 and having a stem 58 extending to the exterior of the casing and having a handle 59 mounted thereon for the purpose of effecting its rotation. A spring 60 surrounds the stem 58 between one end of the casing and the valve 56 for the purpose of firmly holding said valve 56 againstthe disk 54. By rotating the valve 56 through the medium of the handle 59 it will be apparent that the disk 57 can be brought into successive registration with the ports 55. As convenient means for indicating the port in the disk with which the port 57 is in registration I mount on the end of the casing a suitable dial 61 and terminate one end of the handle 59 in a pointer 62. It will be observed in connection with this construction that the disk 54 is removable through the medium of the screws 53 and that in case said disk becomes worn it can be readily replaced with another.

In Figures 12 and 13 I have illustrated an improved form of nozzle employed inmy burner, the same being indicated at B and is formed of a body suitably stepped so that its lower portion projects beyond its upper portion at its forward end. The upper portion of this nozzle is provided with a circular steam receiving chamber 63 which is connected to the steam supply pipe 26 by means of a pipe 64 controlled by a valve 65. The chamber 63 is provided at the extreme bottom of the upper portion of the nozzle with a flared outlet whose inner end is narrower than the diameter of the chamber '63. By this construction the steam under pressure in the chamber 63 is discharged laterally in both directions and contacts with the walls of the flared outlet 65 which in turn assist in forming the steam into a fan shaped film of relatively great extent. The lower portion of the nozzle B is provided with a mixture receiving chamber 66 which is connected with the interior of the atomizing casing by'means of a'pipe 67. The chamber 66 is provided with an upwardly directed discharge outlet 68 opening through the surface of the step, justin advance of the outlet of the chamber 63. Thus it will be seen that the mixture discharging through the outlet 68 will be immediately intersected by the steam discharging through the outlet 65 and the flame produced by the burner will partake of the shape and the extent of the film of steam discharging from the chamber 63.
